Propane conversion in the vehicle fleet at the Idaho National Engineering Laboratory

J.E. Crone-1980-12-01

TL;DRAbstract

One hundred fifty-seven pickups, 9 three-ton trucks, and 3 jeeps were converted from gasoline to propane at the Department of Energy's Idaho National Engineering Laboratory during FY-1980. The conversion to propane has reduced use of gasoline during the FY-1980 transition period by 111,000 gal, and has lowered the fuel cost by $63,000, based on cost of gasohol (which has otherwise replaced gasoline). The Transportation Division estimates total gasoline savings for the year (which include the propane conversion, the switch to gasohol, and a mileage reduction of 8%) to be 196,000 gal of gasoline, or 32% less than FY-1979 consumption. The rate of fuel-cost savings indicate that the payback of the conversion cost for all 170 vehicles ($165,896) will be made approximately 2 to 5 y.
